POCKET-REGISTER.

SPECIFICATION forming part of Letters Patent No. 236,032, dated December28, 1880, Application filed May 13, 1880. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK HORN, of St. Louis, in the State ofMissouri, have invented a new and Improved PocketRegister, of which thefollowing is a specification.

The object of this invention is to provide a simple and convenientdevice for recording or registering ones daily expenses.

The invention consists of two small disks of metal or other suitablematerial, marked with numerals on their outer faces, placed back toback, and united at their edges for about three-quarters of theircircumference, and of a third and movable disk that may be held fixed byaspring, having certain numbers, lines, and indentations on and aboutitsedge, inserted between the other disks and pivoted in place on a pinthat passes centrally through them.

Figure 1 is an enlarged front elevation of the device. Fig. 2 is anenlarged rear elevation of the same. Fig. 3 is an enlarged frontelevation of the central plate or disk. Fig. 4 is an enlarged rearelevation of the central plate or disk. Fig. 5 is an enlarged plan ofthe device.

Similar letters of reference indicate corre-' spondin g parts.

In the drawings, Arepresents the front plate or disk, having its upperedge cut away and indented, as shown at a, the better to exhibit andindicate the numbers on the inner revolvin g plate or disk, O. Thisplate Ais provided with a curved slot, 1), concentric with itscircumference and extending half-way around it, below the centralpivoting-pin, c, and radiating from this slot b arethe indentations d(I. Be-

tween the slot 1) and the circumference of the said disk or plateAthenumbers from 1 to 12, inclusive,are plainly stamped or marked, and withthe dollar-mark preceding them, as shown. A curved spring, D, that ispivoted on the pin 0. between the plates A O, carries on its free end astud, f, that projects through the slot 1) or covers the projecting endof the spring D, and is held, by the action of said spring D, in any oneof the indentations d d in whichit may be placed. An index-hand orpointer, E, is pivoted on the face of the plate A, on the central pin,0, and is designed to be moved to point to the numbers around thecircumference of the said plate.

The back plate, B, is connected to the front plate, A, by means of therim F, while the central pin, 0, that carries the pointer'E, passesthrough all the plates A B O, and is riveted in a burr, g, on the faceof said plate B. This plate B is provided with a curved slot, 71, havingradial indentations 2 similar to those in plate A, and has also a stud,7., operated by a curved spring, H, similar to that connected with plateA. Between the slot hand the circumference of the said plate B thenumbers 10 S0 90 100 are plainly marked or stamped in the order asherein set down. On the inner edge of this plate B, at the point whereitis cutaway, is fastened a small springplate, G, that is designed toengage in the notches m of the central disk or plate, O, to hold saidplate 0 in position, said plate B being recessed, as shown at a, topermit the free movement of said spring G. On the edge of 70 the disk orplate O, which plate revolves on the central pin, 0, are twentyequidistant notches, m, which notches m are numbered from 5 to 100 inarithmetical ratios of 5, and between each notch and the next succeedingone are four radial lines, 1). The notches m are designed to representfive cents each, and the lines 1) to each represent one cent, inregistering.

The register is to be held in the left hand with the face of plate Atoward the operator. The left thumb is then pressed upon the spring G todisengage said spring from the notch m, in which it may be engaged.Then, with the forefinger ot' the right hand the plate 0 is moved sothat any figure or number to be registered may be brought opposite thepoint q of the plate A, which point (1 serves as a marker. hen thisplate 0 thus shows a dollar expended (the number 100 brought oppositethe the marker q) said amount is transferred to the dollar account onthe face of plate A by setting the stud f in the indentation (lpertaining to the figure l, and the plate O is turned back so that thenotch in immediately number 10, and the stud f is then moved into I theindentation d at the left of the figure l on the plate A.

An account or register of all sums of money expended up to a dollar canbe kept on the plate 0. A register of sums from one dollar up to tendollars can be kept on plate A, and from ten to a hundred dollars onplate B, and the index-hand E may be used to point to the number of themonth in which the registering is made.

By this device the record of a persons daily expenses can be keptwithout the troublesome recourse to pencil and paper or memorandumbooksfor every expenditure, and at any time a person can transfer theaggregate amount expended to his account-books.

I do not confine myself to the precise construction of the register asherein shown and described, as it is evident that changes in theconstruction may be made without departing from the principle of myinvention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- As an improved article of manufacture, apocket-register constructed substantially as herein shown and described,consisting of two fixed slotted plates, A B, joined together at theiredges by rim F, and holding between them a plate, 0, revolving on acentral pivot, of spring-actuated indicatingor pointing studs f 7r,spring G, and index-hand E, said fixed plate A being cut away at itsedge and having stamped or otherwise marked on its face the figures from1 to 12, inclusive, said plate B being also cut away at its edge andhaving stamped on its face the numbers from 10 to 100 in arithmeticalratios of ten, and said revolving plate 0 being provided with twentyequidistant peripheral notches and intermediate radial lines, and withnumbers or figures from 5 to 100 in arithmetical ratios of five, asherein set forth.

FREDERICK HORN.
